Note: The gate at Mount Gleason Road at Mill Creek Summit has been closed to vehicles for a number of years. 3N17 is accessible to biking and hiking, following the directions and mileage below and 1700' gain on the road. The Pacific Crest Trail parallels the road from Mill Creek Summit, and avoids the road hike.
DRIVING ROUTE 1
- Drive north on Angeles Crest Highway (SR 2) for 9.5 miles to its
junction with Angeles Forest Highway (N3). Turn left.
- Drive north on Angeles Forest Highway 14.2 miles to Mill Creek
Summit. Turn left on Mount Gleason Road (3N17). Note your odometer and go
- At 6.2 miles, a fork, where the paved road goes into a Los Angeles
County correctional facility.
Take the left fork (dirt) around the detention center.
- At 8.8 miles, a gated paved road goes right (north) just past a
microwave tower. Park at the gate or nearby (don't block the gate).
HIKING ROUTE 1
- From the parking area (6428'), pass the gate and hike up the road to
the summit, a large open area. There is usually no register on this
- To find the HPS register, travel north past the summit area about 0.3
miles on a dirt road to the summit of bump 6502. This is slightly
south of and above where the PCT intersects the dirt road. The
register is in a rocky patch just east of the road.
The Pacific Crest Trail (PCT) crosses the north ridge of Mount Gleason. From
this point it is possible to hike up the ridge less than 1/2 mile to
the summit area.
This makes it possible to hike Mount Gleason via the PCT
from any convenient trailhead along the PCT depending on how long you want
the hike to be.
[by G. Wysup] The Nike fire control radar system was located on the summit.
The admin and launch facilities were at LA Co. correctional facility.
